an expansion project that will enable it to produce about 250,000t/y copper as well as molybdenum and silver. The new line's 36-ft-diameter SAG mill will be fitted with a 13.5-megawatt drive and a 22-megawatt drive will power the line's 28-ft-diameter ball mill. Siemens said the Sinamics cycloconverters that will be installed in the new line are character- ized by low switching losses and high effi- ciency, and the integrated drive and cyclo- converter system will contribute to an expected equipment availability rate of more than 99%. New Integrated System Simplifies Surplus Asset Sales Used heavy equipment seller Ritchie Bros. and AssetWorks, a provider of Enterprise Asset Management software solutions, recently announced the availability of a prepackaged integration between the Ritchie Bros. EquipmentOne marketplace and AssetWorks Surplus Management Software (SMS). Designed to allow AssetWorks' customers the ability to seam- lessly post assets to EquipmentOne, the integration is claimed to reduce the time and effort required to identify, list and sell surplus equipment. AssetWorks' SMS users can identify assets for sale and post those assets along with all the required equipment specifica- tions, condition descriptions and photo- graphs directly from SMS to the EquipmentOne marketplace. They receive daily pricing feedback and final sale data when the sale completes. Automating these processes, according to the compa- ny, can improve accuracy and significantly reduce the time to conduct sales across a number of different asset categories. "Managing assets from acquisition through disposal can be difficult and our solutions have always been aimed at streamlining this process. With our integra- tion to EquipmentOne, we're delivering additional value and really closing the loop on asset management for our customers," said Michael Borello, vice president of AssetWorks. Ritchie Bros. has operations in more than 25 countries, including 44 auction sites worldwide. AssetWorks said its soft- ware solutions help organizations improve access to shared asset data, promoting greater transparency across the organiza- tion, improving service delivery, maximiz- ing asset availability and uptime, and reducing total cost of ownership. Metso to Handle Grinding Mill Maintenance at Two Large Codelco Plants Metso has signed an 18-month services contract with Codelco's Chuquicamata mine for grinding mill maintenance, encompassing changeout of components for 33 ball mills currently operating in the A0 and A1 plants at Chuquicamata. The work will involve changing mill pin- ion-gear assembly and repairs to mill shells. Metso said it plans to repair two mills per month and maintain continuous monitoring of the status of the equip- ment. The value of the contract was not disclosed. The agreement, which covers gear dis- assembly, new gear assembly, pinion assembly, gear alignment (slow rotation) and mantle repair, was scheduled to take effect in April. The contract will create 30 new Metso services jobs in northern Chile. Metso, which has a long history of involvement in the Chuquicamata opera- tions—it supplied three large MP1250 cone crushers and an automatic control system to Chuquicamata in 2012, for example—also noted that its 750 employ- ees in Chile have worked more than two years without a lost-time incident. The Association of Major Suppliers for Mining in Chile recognized Metso for its safety results in 2013. FLSmidth Wins Mongolian Copper EPCM Contract FLSmidth has received orders worth approximately $43 million from the Mongolian company, Mongolyn Alt (MAK) Group, to supply engineering, procurement and site construction services for the Tsagaan Suvarga copper-molybdenum con- centrator project. This greenfield plant, with a capacity of 40,000 mt/d of ore, will be located in the central part of the Oyu Tolgoi South Gobi porphyry copper belt in southeast Mongolia. FLSmidth is currently supplying all of the main process technology for the project under a separate, previously awarded con- tract announced in 2011. MAK is the third largest company in Mongolia with diverse business activities, including coal and gold mining operations. The Tsagaan Suverga project will be the group's first copper con- centrator. In February 2012, FLSmidth was awarded an order from MAK for supply of a greenfield cement plant.
